Fluorescent Beads

(Should also try MultiSpeck beads M 7901)


  • use polylysine slides so beads stick
  • 5 uL beads total (can mix colors on one slide)
  • 12 uL water; mix well
  • dry on a slide warmer (or hot plate at about 50C)
  • draw a circle on the bottom of the slide around the dried material
  • put 1 drop mounting medium over dried spot (gloppy! can't pipet!)
  • coverslip
  • nail polish
